Title: Resistance spot welding method
Inventor: IZUNO KYOSUKE
IPC: B23K11/11
Filed: 2019-11-20
Abstract: To provide a resistance spot welding method capable of efficiently molding a weld nugget while suppressing occurrence of spatters.SOLUTION: In initial energization of resistance spot welding, energization between electrodes is stopped in a status that "1.2≤an external dimension of an alloy layer/an external dimension of a welding nugget≤1.5", and main energization is performed after a prescribed interval is lapsed. Thereby, the welding nugget is cooled during the interval, and an electric resistance value in an area where the welding nugget is molded can be reduced. Therefore, local expansion of the welding nugget is suppressed even when the main energization is started after that, and generation of spatters can be suppressed. Consequently, limitation of spatter generation in the welding current value in the main energization can be raised, and the welding nugget can be efficiently molded while suppressing spatter generation.SELECTED DRAWING: Figure 5
